SPECIIICATIONformingpm-t of team Patent No. 415,111, dated January 20, 1891.

' Application filed April 28,1890. Serial 1%. 349,167. on s ecimens/0':

To all whom it may concern:

Be it known that I, LUDWIG GRoTE, a subjeot of the Emperor of Germany, residing at Dresden, Saxony, in the German Empire,

5 have invented a new and useful Composition for Treating Articles Made from Paper or the Like, of which the followingis a specification. The object of this invention is an improved composition for the treatment of handles,

' "to tool-shafts, and similar articles made of papre era 1 o 'beeswax. Thispasteisthen added to the -paper,wh1ch may be accom- 'plished by two difierent methods: First, or-

. =5 dinary a er- 111 may be employed, such as is used Eor the manufacture of paper or card-' board, it being immaterial whether it is made of ra s, cellulose, straw or any other suitable.

su Estance, thls paper-pulp beingmixed with.

0 the paste above referred to, and then molded in suitable molds or dies into the men shape; or, second, read -made a er may be utilized by being cutmto long strips, which are then drawn t roug e pas a ove re- 35 ferred to, and thus impregnated therewith.

After this they are wound round a cylindrical 7 or conical core or mandrel and compressed thereon by means of one or more rollers, and the tubes thus obtained are finally turned to the desired shape on an ordinary lathe.

The articles obtained by either the first or second of the methods just described are di ed into a solution of say, twenty-five parts of su ar ten 'partsoi slaked lime and sixty-five parts of water an t on a owed to .dry. This solution prevents salt precipitates forming on the surface of the article, owing to the use of water-glass. The articles obtained by this process are remarkable for their density, and are practically indestructible, while at the same time they are very yielding. In' tool handles or shafts manufactured in this manner it is not necessary, for example, to bore or burn an openingfitting enactly the size of the tool, it being easy to force the core of a tool measuring twentyfive millimeters in diameter into an opening of five millimeters diameter, which will readily spread out to fit the tool without any risk of its breaking.

I claim- 1. A composition for the purpose set forth, comprising starch, wat e lass, and a fatty substance, substantially as described.

2. The composition for the purpose set forth, comprisin a starchy substance, water-glass, and bee v substantially as described.

. In witness thereof Iafiix hereunto my signature in presence of two witnesses.
